How Mississippi Plumber license verification works
A Plumber in Mississippi is licensed by the MS Contractor Licensing Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.
Fields returned for this board: license_number contractor_type status expires first_issue classifications qualifying_names officers company address phone fax minority.
Board note: MS-MSBOC: Board's Consolidated Search (ColdFusion/Lucee, plain HTTP, no captcha). POST ConsolidatedResults.cfm?...&Advanced=1 with Lic=<5 chars> (one hit -> 302 to Detail.cfm) or QualName=<qualifying name, contains>; GET Detail.cfm?ContractorID=. Mississippi licenses the business; the person is the Qualifying Name per classification (electrician = ELECTRICAL WORK / RESIDENTIAL ELECTRICAL, plumber = PLUMBING, hvac = HVAC / HEATING / MECHANICAL). Commercial and residential licences can share a number (20838 vs 20838-SC) -> the connector opens both and keys on the qualifying name. Statuses Licensed / Licensed Expired / Revoked / Suspended.
